Howdy - I'm rebuilding my Aisin 35240 carb on my 83 2WD RN44 2.4 5-speed. I'm essentially done but through a bit of carelessness in disassembly, I ended up with a circular black-colored spring that I can't figure out where it goes. It's 10mm in diameter and there's only one shaft on the carb (see pic) that it would fit on, but no matter how I try, it seems to not to need to go there. I've reassembled the carb "dry" without gaskets to check its functioning before glueing it all together. It seems to set the choke, release the choke, fast idle cam moves good, etc. fine. I vacuum tested the various diaphragms, all are ok. Resistance at the choke heater is fine. Now I'm not sure this spring goes on the carb at all. Anyone know about this spring or have an exploded diagram of this shaft's pieces and where they go? My last resort I guess, is to install it and just see how or how bad the truck runs LOL... THANK YOU!

Thanks for the speedy reply. Unfortunately I've already seen this diagram and it's not detailed enough. The shaft that holds the fast idle cam and a couple of other things is circled in this pic. This shaft is the only one that my mystery spring fits on; it's too small for the other shafts. It's a blow-up of this shaft component that I need, or someone who remembers seeing this spring from one of their rebuilds. Again, thank you, and have a good one!
